Bug#567098: linux-image-2.6.26-2-ixp4xx: adm8511/pegasus usb ethernet device loses mac on nslu2 when cold-plugged
Devin, did you report this issue upstream?
Since you have the hardware, it makes sense to work with upstream
directly.
If you're not interested in reporting it upstream, I'll close this bug
report. (Note that this is my 3rd ping.)
